Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a toilet room air conditioning unit for performing air conditioning in a toilet room.

[Prior Art] Conventionally, the output of the air adjustment by the air adjustment unit in the toilet room largely depends on the equipment capacity provided in the air adjustment unit.
Medium or weak output level is selected by the user, or the room temperature in the toilet room is detected by a temperature sensor such as a thermistor and feedback control is performed on the device output to adjust the output.

[Problems to be Solved by the Invention] In the conventional example as described above, since the output of the device is controlled by detecting the room temperature, the comfort of the user is not so great in controlling the device. There is no particular consideration, especially at the start of operation of the equipment, the wind speed is high until the room temperature is adjusted, and when heating the toilet room, the warm air that hits the person sitting on the toilet seat continues for a long time. The temperature is not so comfortable for the human body because it is sent too hot and when it is cooled, the cold air that hits the human body is sent too continuously for a long time and is too cold. In addition, even in equipment that has an output selector switch, its output level is set to a certain level by the capacity of the equipment, and it does not take into consideration the comfort of the human body. When doing, there was a problem that it gives the user an unpleasant feeling.

The present invention is intended to solve the above problems,
It is an object of the present invention to provide an air conditioning unit in a toilet room, which can efficiently and quickly adjust the air in the toilet room for the user to be comfortable.

[Means for Solving the Problems] In order to achieve the above object, the toilet room air conditioning unit according to the present invention has an air conditioning unit 2 having a blower opening 1 for air conditioning disposed in a toilet room 3. ,
The wind speed control means 4 is provided so that the wind speed of the air blown from the air blower opening 1 to the person seated on the toilet seat is about 1 m / s for about 2 minutes after the start and then about 0.5 m / s. .

[Operation] The amount of air blown from the air blow port 1 of the air conditioning unit 2 to the person seated on the toilet seat is set to 1 m / s for about 2 minutes after the start of air blowing by the wind speed control means 4, and then to about 0.5 m / s. By doing so, it is possible to automatically weaken the blown air for adjusting the air from the blower opening 1 hitting the seated person after a certain period of time, and the strong blown air is not continuously blown. Efficient and quick air conditioning can be performed without sacrificing comfort.

[Embodiment] As shown in FIG. 1, an air conditioning unit 2 arranged in a toilet room 3 is formed in a box shape having a ventilation port 1 for air conditioning, and has a ventilation section 5 and a heat An exchange 6 and a switching damper section 7 are provided respectively. The blower unit 5 is a blower fan 5a, and the blower fan 5a communicates with an intake port 8 provided in the upper portion of the air conditioning unit 2.
Then, by operating the blower fan 5a, the air in the toilet room 3 can be sucked from the intake port 8. A heat exchanger 6 is provided below the blower unit 5 as shown in FIG. This heat exchanger 6 is a heat pump type heat exchanger, and can change the air blown from the air blower fan 5a into warm air by setting it in a heat radiating state. Can be changed to cold air. Below the heat exchanger 6, a switchable damper part 7 is provided which can be switched. This switching damper part 7 is communicated with a cold air blowing port 1a provided in the substantially central part of the air conditioning unit 2, and in winter, the switching damper 7a is switched to an open state to blow the fan 5a.
The cool air sent from the heat exchanger 6 via the heat exchanger 6
It is designed so that it can be ejected from 1a. At this time, the position of the cold air blowing port 1a is provided at a position where the cold air is blown out near the face of the person when the person is sitting on the toilet seat in the toilet room 3. In this way, by providing the cold air blowing port 1a at the position where the cold air blown out is blown out near the face, the cold air can be blown out near the face where the coolest feeling is felt in the summer. You can feel the coolness even if the whole is not cooled. A warm air blower port 1b is provided below the cold air blower port 1a and below the air conditioning unit 2. At this time, the warm air blowing port 1b is provided at a position where the warm air is blown to the feet of the person when the person sits on the toilet seat in the toilet room 3. The warm air is heated by the heat exchanger 6 in a heat-dissipating state by blowing the air blown from the blower fan 5a and ejected as warm air from the warm air blowing port 1b. At this time, the switching damper 7a is closed,
The warm air is not blown out from the cold air blowing port 1a. Since hot air can be ejected to the feet in this way, it is possible to heat the inside of the toilet room 3 from the feet that are easily cooled in winter with the warm air, and the entire toilet room 3 is warm even if it is not completely heated. You can feel it. Also, at this time, when heating the toilet room 3 in winter, warm air is emitted from the feet to heat the inside of the toilet room 3, so the hot air should flow from the bottom to the top. Therefore, it is possible to efficiently heat the inside of the toilet room 3, and in the summer, when cooling the inside of the toilet room 3, the cool air will flow downward from the upper part near the face, so that the toilet room can be efficiently heated. Cooling in 3 can be performed. A cylindrical horizontal air passage 9 is formed on the inner side of the warm air blowing port 1b. The horizontal air passage 9 is provided so as to communicate with the warm air blowing port 1b, and a ventilation vent hole 9a that opens upward is provided on the upper surface of the rear portion located on the opposite side of the warm air blowing port 1b. There is. An auxiliary heat source unit 10 such as a heater is provided inside the horizontal air passage 9, and the auxiliary heat source unit 10 changes the air blown from the blower fan 5a into warm air and blows it out from the warm air blowing port 1b. I am able to do it. With this configuration, the warm air blown from the warm air blowing port 1b can be changed into warm air in the cylindrical horizontal air passage 9 and then blown, and even if the capacity of the small blower fan 5a is high, The wind can be ejected from the warm air blowing port 1b. That is, when the blast is warmed to be warm air, the warm air tries to rise, but by changing the hot air into the warm air in the tubular horizontal air passage 9 and ejecting the hot air, the warm air rises by the tubular horizontal air passage 9. As a result, the warm air can be ejected from the warm air blowing port 1b even with the small blowing fan 5a. At this time, wind speed control means for controlling the amount of air blown inside the air adjusting unit 2 so that the amount of hot air and cold air blown out from the hot air blower port 1b and the cool air blower port 1a can be adjusted. 4 is provided and this wind speed control means 4
As shown in Fig. 3, the wind speed of the air blown from the warm air blower opening b and the cool air blower opening 1a is about 2 minutes after the start of the blowing.
It was set to 1 m / s, and then set to about 0.5 m / s. In addition, the output of the heat exchanger 6 is set to about 1 Kw for about 2 minutes after the start of operation, and then about 0.5 Kw is set to output so that the temperature of hot air and cold air can be adjusted. There is. That is, as shown in FIG. 4, when the air in the toilet room 3 is adjusted, by operating the switch operation unit 4a of the air adjustment unit 2, a control signal is sent to the blower control unit 4c and the heat source control unit 4d via the timer 4b. The heat exchanger 6 and the blower fan 5a are operated. At this time, the heat source control unit 4d is set high, the output of the heat exchanger 6 is set to about 1 Kw, the blower control unit 4c is set to be strong, and the wind speed from the blower fan 5a is set to about 1 m / s. Is done. Then, after 2 minutes have elapsed from the start of operation, the timer 4b outputs a time-up signal to the heat source control unit 4d and the blower control unit 4c to switch the heat source control unit 4d and the blower control unit 4c to low and weak, respectively. The speed of air blown from the blower fan 5a is set to 0.5 m / s, and the output of the heat exchanger 6 is controlled to 0.5 Kw. With such a configuration, the wind speeds of the warm air and the cold air jetted toward the person at the start of air adjustment can be automatically slowed down about 2 minutes after the start, and the output of the heat exchanger 6 is started. By dropping after about 2 minutes, the temperature can be moderated, and air conditioning can be performed quickly and efficiently without impairing comfort. In the embodiment shown in FIG. 3, the case where the wind speed after about 2 minutes and the output of the heat exchanger 6 are changed stepwise is shown, but as shown by the broken line if there is no problem in the configuration of the equipment. It may be changed continuously and smoothly. The space in the toilet room 3 is 0.9m wide and is flowing
Example of the case where the distance from the blower opening 1 of the air conditioning unit 2 disposed in the toilet room 3 to the person seated on the toilet seat is 1.8 m and the height is 2.4 m from 0.3 m to 0.7 m It is shown in FIG. At this time, the room temperature is 30 ° C to 36 ° C in summer, and 5 ° C to 10 ° C in winter. When cooling the toilet room 3 in the summer, the temperature in the toilet room 3 is about 33 ° C immediately after entering the room, and about 27 ° C after 30 seconds by blowing cool air from the cool air blowing port 1a to cool the room. From 29 ℃
It can be lowered to. At this time, the cooling air blown from the cooling air blowing port 1a is about 1 m / s, and after 2 minutes, the room temperature drops from a comfortable temperature of about 23 ° C. to 25 ° C. The ventilation control means 4 automatically switches the wind speed to 0.5 m / s so as to maintain the room temperature at 23 ° C. to 25 ° C., thereby maintaining a comfortable feeling. When heating the toilet room 3 in the winter, the room temperature in the toilet room 3 is approximately immediately after entering the room.
The temperature is 10 ° C, and it is possible to raise the temperature from about 17 ° C to 21 ° C after 30 seconds by ejecting warm air from the warm air blowing port 1b and heating. At this time, the warm air blown from the warm air blowing port 1b is about 1 m / s, and after 2 minutes, the room temperature rises from a comfortable temperature of 25 ° C to 27 ° C. Then, the ventilation control means 4 automatically switches the wind speed to 0.5 m / s so as to maintain 25 ° C. to 27 ° C., thereby maintaining a comfortable feeling.
The intake port 8 is provided with a filter 11 capable of preventing dust, deodorizing, and aroma. With such a structure, when the air in the toilet room 3 is sucked from the intake port 8, the dust is prevented immediately after the suction. Therefore, it is possible to prevent dust and dirt from adhering to the heat exchanger 6 and the blower fan 5a, and to deodorize and aroma the air in the toilet room 3 at the same time.

[Effects of the Invention] As described above, the present invention controls the wind speed of the air blown from the air blower to the person seated on the toilet seat to about 1 m / s for about 2 minutes after the start, and to about 0.5 m / s after that. Since the wind speed control means is provided, the wind speed control means automatically slows down the wind speed of the air blown from the air outlet to make it strong against people entering the toilet room when adjusting the air in the toilet room. It is possible to automatically and quickly and efficiently adjust the air in the toilet room without the comfort being deteriorated, because the blast is not continuously sent to be too hot or too cold.
